This article first introduces the general situation of ISO, ITU-T, IEEE, W3C and other international standardization organizations, and sorts out the status quo of the blockchain standardization working groups of mainstream international standardization organizations. All blockchain-related standards under development have been analyzed for the characteristics of international blockchain technology standards and industry application standards. Through data analysis, the overlaps, differences and conflicts in the field of international blockchain standard formulation are sorted out, and suggestions for blockchain standardization work in the application and development of blockchain technology standardization by international organizations and industries are put forward. The plans and layouts of future international standards are summarized to help the development of the international standardization of blockchain.
